Oh damn, yeah, I'm after one of those. (Given the price of the Linnstrument and Haken Continuum, I was interested to see that the Sensel Morph recently acquired MPE. There's also the Madrona Soundplane if you can get hold of one, and that about wraps it up for that kind of controller.)

Unfortunately C-thru Music no longer make these and they're not easy to find, leaving the Opal as the only game in town for this "Harmonic Table" concept. (Beautifully made but with a price tag to match.)

(In other isomorphic news...Dualo folded without ever producing the larger Du-touch L funded on Kickstarter...to the wrath of the punters who lost their money. But some of the original team have recently re-emerged as Intuitive Instruments to keep the dream alive, so at least people can get their smaller Du-touch S serviced if needs be. I need to get mine fixed as it happens, but the last instrument I sent to France for repair disappeared without trace and I haven't quite forgiven the French yet, so...we'll see.)
